Bainitic Tech Invented

China established its first bainite steel company yesterday in Beijing, a move hailed by economists as set to improve the country's ability to manufacture top quality steel and steel products.

Beijing Bainite Steel Company (BBSC) is backed by China National Metals and Minerals Import and Export Corp (Minmetals), one of the country’s first 55 trade conglomerates，and the prestigious Qinghua University.

BBSC has state-of-the-art Mn-B air cooling bainitic steel technology which is unique to China and patented throughout the world.

The technology, invented by Fang Hongsheng professor of Qinghua University, has been regarded by the US Steel Company as the best type of bainitic steel in the world for its low cost and high quality.

Bainitic steel was discovered in the 1930s and is deemed superior to other kinds of steel in making grinding balls and cast steel used mainly in mines and the electric industry. It is energy- saving and causes little chemical pollution.

So far, there are three other major types of bainitic steel in the world, namely, Mo-B series, Moderate series and Non-Moderate series. They all consume too many precious elements such as molybdenum (Mo)，tungsten (W) , nickel (Ni) and chromium.

But the Mn-B type of bainitic steel does not contain Mo, W or Ni. It mainly uses man¬ganese which is not a rare element.

With the technology, China has got the upper hand over other major producers like the United States which can only make low-carbon bainitic steel used for warships and cars. Now China is also able to produce medium and high-carbon bainitic steel which is used to manufacture the much-sought-after wear-resistant tools , such as grinding balls.

While bainitic steel is still rare in the world markets because of its high costs, BBSC will enable China to start mass production. The company has established three bainitic steel plants，three grinding ball plants and two bainitic cast steel plants in the country. It also boasts a cluster of factories manufacturing various springs, sophisticated die blocks, auto front axles and other machine components.

Minmetals, which has established 70 wholly-owned and joint ventures in 25 countries and regions, will serve as an effective channel for BBSC's exports.

So far, BBSC has forged links with Australia, New Zealand, Canada, the United States and Southeastern Asian countries to provide them with bainitic grinding balls and wear-resistant cast steel.

The success of the company shows how it is supporting China's effort to improve the quality of its export commodities in 1991 〜1995.

贝氏炼钢法的发明

中国昨天在北京建立了第一家贝氏钢铁公司，此举被经济学家们称赞为认真着手改进生产优质钢和制造优质钢产品能力的措施。

北京贝氏钢铁公司（BBSC）得到中国首批55个贸易联合企业之一——中国国家金属和矿产品进出口公司(Minmetab)和著名的清华大学的支持。

BBSC具有现代化的含锰贝氏钢（Mn-B）空气冷却贝氏钢冶炼技术，这是中国独有的技术，并在全世界获得专利。

这项技术是由清华大学方宏生（译音）教授发明的；由于成本低质量好，美国钢铁公司认为用这项技术炼出的钢是世界上最好的一种贝氏钢。

贝氏钢是30年代发现的，并被认为在制造主要用于矿山和电气工业的磨球和铸钢方面优于其他类型的钢，它既节约能源，又几乎没有化学污染。

迄今，世界上还有另外三种主要的贝氏钢，即含钼（贝氏钢）系列、中常系列和非中常系列。这三种贝氏钢消耗的像铕(Mo)、钨(W)、镍(Ni)和铬(Cr)之类的贵重元素都太多。

但是，含锰贝氏钢(Mn-B)不含钼、钨或镍，它只用到非稀有元素锰。

有了这种技术，中国就取得了对其他主要钢铁生产国像美国的优势，美国仅能生产制造军舰和汽车所需的低碳贝氏钢。今天，中国还能生产中碳贝氏钢和髙碳识氏钢，用来加工制造市场上供不应求的耐磨工具，供磨球。

由于成本高，贝氏钢在世界市场上还不多见，而BBSC却使中国能开始批量生产。该公司已在全国建立了三个贝氏钢铁厂、三个磨球厂和两个贝氏铸钢厂。它还以拥有一批制造各种弹簧、复杂模板、汽车前轮轴及其他机器零部件的工厂而引以为豪。

Mimnetals巳在25个国家和地区建立了70家独资和合资企业，它将有效地起到BBSC出口渠道的作用。

到目前为止，BBSC已同澳大利亚、新西兰、加拿大、美国及东南亚国家建立了联系，向这些国家供应贝氏钢磨球和耐磨铸钢。

BBSC的成功，表明该公司在支持中国在1991〜1995年期间改进出口产品质量上起着多么大的作用。
